Purpose of this thread and my title question are purely theoretical. I hope people keep this premise in their mind, if and when this thread starts to have opinionated comments favoring or bashing either one of the formats. Feel free to tell your opinion about CD or LP, even though the purpose of this thread is to find an answer to my theoretical question. The answer I'm primarily looking for is just a number. A number indicating the maximum, widest possible, dB range. The dB range between noise floor and loudest possible sound that can be recorded. But of course, making a recording in a studio is very complicated process, so if you provide the numeral answer I'm looking for, it would be very nice if you could give some explanation in what kind of circumstances your given answer can be achieved. I'm hoping some one working in the recording industry could provide verified answers, but if anyone else has the answers that I'm looking for, then of course, feel free to tell. But, if you are not a professional, it would be nice if you could tell where you got your information from. So, my questions. Which one has greater dynamic range, CD or LP? How big is the theoretical maximum dynamic range on CD, and how big is it on LP?
